Answer:
y = 2x/3 + 1
Step-by-step explanation:
2(-3n-5)-5(4n-8)
(-6n-10)+(-20n+40)
-26n-30
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have

Substitute the values and solve for k


therefore
the equation of the line is equal to

The answer to this question is C
No of substes is given by 2^n where n is the no of elements.
Here, n = 3
Therefore, number of subsets = 2^3 = 8
